Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. They are organic chlorine compounds with the formula C12H10−xClx; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment.
Polychlorinated dibenzodioxins (PCDDs), or simply dioxins, are a group of long-lived polyhalogenated organic compounds that are primarily anthropogenic, and contribute toxic, persistent organic pollution in the environment.
A tampon is a menstrual product designed to absorb blood and vaginal secretions by insertion into the vagina during menstruation. Unlike a pad, it is placed internally, inside of the vaginal canal. Once inserted correctly, a tampon is held in place by the vagina and expands as it soaks up menstrual blood. However, in addition to menstrual blood, the tampon also absorbs the vagina's natural lubrication and bacteria, which can change the normal pH, increasing the risk of infections from the bacterium Staphylococcus aureus, which can lead to toxic shock syndrome (TSS). TSS is a rare but life-threatening infection that requires immediate medical attention.
Biosolids are solid organic matter recovered from a sewage treatment process and used as fertilizer. In the past, it was common for farmers to use animal manure to improve their soil fertility. In the 1920s, the farming community began also to use sewage sludge from local wastewater treatment plants. Scientific research over many years has confirmed that these biosolids contain similar nutrients to those in animal manures. Biosolids that are used as fertilizer in farming are usually treated to help to prevent disease-causing pathogens from spreading to the public. Some sewage sludge can not qualify as biosolids due to persistent, bioaccumulative and toxic chemicals, radionuclides, and heavy metals at levels sufficient to contaminate soil and water when applied to land.
Pentachlorophenol (PCP) is an organochlorine compound used as a pesticide and a disinfectant. First produced in the 1930s, it is marketed under many trade names. It can be found as pure PCP, or as the sodium salt of PCP, the latter of which dissolves easily in water. It can be biodegraded by some bacteria, including Sphingobium chlorophenolicum.
Milorganite is a brand of biosolids fertilizer produced by treating sewage sludge by the Milwaukee Metropolitan Sewerage District. The term is a portmanteau of the term Milwaukee Organic Nitrogen. The sewer system of the District collects municipal wastewater from the Milwaukee metropolitan area. After settling, wastewater is treated with microbes to break down organic matter at the Jones Island sewage treatment plant in Milwaukee, Wisconsin. The byproduct sewage sludge is produced. This is heat-dried with hot air in the range of 900–1,200 °F (482–649 °C), which heats the sewage sludge to at least 176 °F (80 °C) to kill pathogens. The material is then pelletized and marketed throughout the United States under the name Milorganite. The result is recycling of the nitrogen and phosphorus from the waste-stream as fertilizer. The treated wastewater is discharged to Lake Michigan.
Sodium polyacrylate (ACR), also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH2−CH(CO2Na)−]n and has broad applications in consumer products. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water. When dissolved in water, it forms a thick and transparent solution due to the ionic interactions of the molecules. Sodium polyacrylate has many favorable mechanical properties. Some of these advantages include good mechanical stability, high heat resistance, and strong hydration. It has been used as an additive for food products including bread, juice, and ice cream.
Chemetco was formerly one of the largest United States refiners of copper from recycled or residual sources.
Bleaching of wood pulp is the chemical processing of wood pulp to lighten its color and whiten the pulp. The primary product of wood pulp is paper, for which whiteness is an important characteristic. These processes and chemistry are also applicable to the bleaching of non-wood pulps, such as those made from bamboo or kenaf.
Havertown Superfund is a 13-acre polluted groundwater site in Havertown, Pennsylvania contaminated by the dumping of industrial waste by National Wood Preservers from 1947 to 1991. The state first became aware of the pollution in 1962 and initiated legal action against the owners in 1973 to force them to cleanup the site. The Environmental Protection Agency (EPA) ranked the site the eighth worst cleanup project in the United States. The site was added to the National Priorities List in 1983 and designated as a Superfund cleanup site in the early 1990s. Remediation and monitoring efforts are ongoing and the EPA transferred control of the site to the Pennsylvania Department of Environmental Protection in 2013.
More thorough treatise of all groups with similar actions and binding to aryl hydrocarbon receptor is given in Dioxins and dioxin-like compounds.
Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms. Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem levels.
Dioxins and dioxin-like compounds (DLCs) are a group of chemical compounds that are persistent organic pollutants (POPs) in the environment. They are mostly by-products of burning or various industrial processes - or, in case of dioxin-like PCBs and PBBs, unwanted minor components of intentionally produced mixtures.
The environmental effects of paper are significant, which has led to changes in industry and behaviour at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper became a relatively cheap commodity, which led to a high level of consumption and waste. The rise in global environmental issues such as air and water pollution, climate change, overflowing landfills and clearcutting have all lead to increased government regulations. There is now a trend towards sustainability in the pulp and paper industry as it moves to reduce clear cutting, water use, greenhouse gas emissions, fossil fuel consumption and clean up its influence on local water supplies and air pollution.
Imperial Oil is a current Superfund site located off Orchard Place near Route 79 in Morganville, Marlboro Township, Monmouth County, New Jersey. This site is one of 114 Superfund sites in New Jersey. It is in the U.S. Environmental Protection Agency (EPA) Region 2 Superfund area of control and organization. The 15-acre (61,000 m2) Imperial Oil Co./Champion Chemicals site consisted of six production, storage, and maintenance buildings and 56 above-ground storage tanks.
Environmental impacts of cleaning products entail the consequences that come as a result of chemical compounds in cleaning products. These cleaning products can contain chemicals that have detrimental impacts on the environment or to people.
Between 1947 and 1977, General Electric polluted the Hudson River by discharging polychlorinated biphenyls (PCBs) causing a range of harmful effects to wildlife and people who eat fish from the river. Other kinds of pollution, including mercury contamination and cities discharging untreated sewage, have also caused problems in the river.
Moyer's Landfill was a privately owned landfill in Collegeville, Pennsylvania, United States. It was originally farmland outside the town. In the 1940s, the owner started accepting trash and municipal waste as a way to make additional money. The original landfill was 39 acres and did not have a liner to protect the land from contaminate. A liner was added to a new section in the late 1970s. Over time, the landfill accepted sewage, and industrial wastes which contained hazardous substances in addition to municipal waste. The site was closed by the EPA in 1981, and was one of the first "Superfund" sites added to the National Priorities List.
Brook Industrial Park (BIP) is an industrial area occupying 4.5 acres of the Borough of Bound Brook, New Jersey, in the United States of America. It is located on the northern bank of the Raritan River. Industrial, chemical and pesticide operations began in 1971 and eventually lead to the contamination of groundwater and exposure of workers to harmful dioxins. Throughout 1980 to 1988 the United States Environmental Protection Agency (EPA) and the New Jersey Department of Environmental Protection (NJDEP) conducted studies to determine if there were any threats being posed on the workers, community or environment by the BIP companies in their disposal of processed and stored chemicals.
Environmental law in New Jersey consists of legislative and regulatory efforts to protect the natural environment in the State of New Jersey. Such efforts include laws and regulations to reduce air and water pollution, regulate the purity of drinking water, remediate contaminated sites, and preserve lands from development, particularly in the Pinelands of southern New Jersey and the Highlands in the north of the state. Environmental laws in New Jersey are enforced primarily by the New Jersey Department of Environmental Protection (NJDEP).
